Now white will capture the c4-rook with a winning Q-side pawn structure! Pushing the b-pawn will give an easy win!

Yes, you're right, Ba2 is winning even in line that I found. So the best line is: 1.Qxe5!!! fxe5 2.Rf1 Qe7 3.Bd1 Rc4 4.Bb3 b5 5.a4! a6 6.Ba2! and black is completely lost.

I remember seeing this same position on CCC a while back. I think White has a pretty easy time winning in a variety of ways. For example in the above line 1.Qxe5 fxe5 2.Rf1 Qe7 3.Bd1 Rc4 4.Bb3 b5 5.Bxc4 (instead of 5.a4) 5...bxc4 6.b3 should also win pretty easily for White. You can pretty much ignore all the program evaluations, since Black's rook and king are forever stuck in the corner, and likewise Black's queen mobility is severely hampered by the mate threat. Material is mostly irrelevant here. Computer's also have severe trouble due to the horizon effect, since it will take a little time for White's queenside pawns to get far enough down the board to create havoc. But when they do (and there is no way for Black to stop this) ..... game over.

Robin, do you have the entire game score for this position? I've tried to find it on the net but to no avail so far

Best ,

Hi Terry,

Lewis Grimm already posted a game score up a few posts that I assume is correct. I am not sure where he found it, it doesn't seem to be in the big electronic databases. Lewis, can you name your source?

Opps! I just found it thanks.... Anyway, I've got it for my records.

He either got it from a chess database he owns or from a chess book.
If he found it on the web, I'd like to know where as well!
